Behaviour of nionikral-70 in low-cycle fatigue
(Institut za ispitivanje materijala, Beograd, 2017)
Experimental research on the behaviour of high-strength low-alloy steel ( HSLA)exposed to low-cycle fatigue (LCF) with controlled and fully reversible strain (Delta epsilon/2 = const, R epsilon =epsilon(min)/epsilon(max) ...
Experimental study on the stresses at the i-beam end-plate moment connection
(Institut za ispitivanje materijala, Beograd, 2019)
The paper deals with experimental study of the stresses at the bolted end-plate moment connection. The design parameters are adopted to include prying effects in joint. A stress level is obtained in the elements where the ...
